3 Claims.

This invention relates to a frame construction for gliders or similar furniture and has particular reference to means for connecting a cross member to upright side frames to secure a con- 5 struction of maximum rigidity.

It is desirable to make gliders or the like, the frames of w hich'are of metal, as light as possible but nevertheless as rigid as possible While at the same time making provision for ready assembly and disassembly so that the relatively heavy pieces may be moved. Desirably, for example, the stationary frame should be as simple as possible, the simplification not only being produced by forming the parts in skeleton fashion but also by eliminating as much as possible of the cross members connecting the ends which are depended upon for the support of the seat..

It is the broad object of the present invention to provide means for connecting a cross member to two upright end frame elements so that the elements are rigidly held in upright position and in stable condition although they are subjected to considerable loads and variable stresses as occur during the swinging of a glider or the like.

A further object of the invention is the provision of an arrangement in which the various parts may be disassembled and reassembled readily. I

a Detailed objects of the invention will be apparent from the following description read in conjunction with the accompanying drawing in which:

Fig. 1 'is a perspective View of one end of a glider frame; and

Fig. 2 is a perspective view showing the details of the connecting means between a cross member and one upright side frame. I

A side frame of the glider is indicated at 2, this frame being provided with suitable supporting legs and serving to pivotally suspend by means of suspension members 4 and 6, the said frame 8 which carries an arm rest H3 preferably overlying the side frame as indicated so that a person seated on the glider will not come into contact with stationary parts.

Connection between the side frames is provided by a cross member l2 which in the present instance is shown as an angle member I2 riveted to connecting members M by rivets passing through openings it in said connecting members. Each of the connecting members is formed of sheet metal which may, for example, be approximately inch thick and consists of a top, depending portions l8 arranged to extend outwardly from the frame element after assembly and'side flanges 20 carried by the depending portions and arranged to extend in parallelism with a flat plate 24 of the frame element. The flanges 20 have downwardly converging side edges indicated at 2| which are received within downwardly converging troughs provided by tongues 22 punched out of the plate 24.

The plate 24 has also extending laterally therer from a tongue 26 the end of which is upturned and receivable in a slot 28 formed in the top of the member M.

The construction just described is very rigid and provides a very strong connection between the cross member l2 and the plates 24; The tongue 26 does not arrest the downward movement of the member I4 relative to the corresponding end plate 24 so that the member'moves to a position in which the flanges are wedged into the troughs provided at 22, This connection alone might not be sufficient for absolute rigidity inasmuch as a tendency of the upright frames to bend outwardly might cause the flanges 2|] to distort the tongues 22. The engagement of tongue 26 within the opening 28 prevents this action by obviating any possibility that the cross member might move laterally relatively to the upright frame. It will be obvious, accordingly, that while the tongue 26 does not serve to limit relative vertical movements it does effectively prevent destructive flexure of the tongues 22.

It will be obvious that details of the construc tion may be changed without departing from the invention as defined in the following claims.

What I claim and desire to protect by Letters Patent is:

1. Means for connecting a cross member at each of its ends to an upright frame element including a member having a top secured to the cross memher, and side flanges secured to said top and having downwardly converging edges, said flanges lying substantially in the same plane, said frame element having downwardly converging troughs opening towards each other into which said flanges may be wedged, said top being provided with an opening, and a hook extending from the frame element and engaging within said opening.

2. Means for connecting a cross member at each of its ends to an upright sheet metal frame element including a sheet metal member having a top secured to the cross member, and side flanges secured to said top and having downwardly converging edges, said flanges lying substantially in the same plane, said frame element having tongues extending therefrom providing downwardly converging troughs opening towards each other into which said flanges may be wedged, said top being provided with an opening, and a tongue extending from the frame element providing a hook engaging within said opening.

3. Means for connecting a cross member at each of its ends to an upright sheet metal frame element including a sheet metal member having a top secured to the cross member, portions depend- 10 ing from said top arranged to extend outwardly from the frame element, and side flanges on said portions arranged to lie flatagainst said frame element and having downwardly converging edges, said frame element having tongues extending therefrom providing downwardly converging troughs into which said flanges may be wedged, said top being provided with an opening, and a tongue extending from the frame element providing a hook engaging within said opening.
